Embodiment Construction

[0014] The technical solutions of the present invention will be further described below in combination with specific preferred embodiments.

[0015] A production method for preparing nano calcium carbonate / wood composite material, comprising the following steps:

[0016] (1) Wood pretreatment: After peeling and sawing the log into required size specifications, dry it at 50°C-80°C for 8-24 hours, and control the moisture content of the wood to 8%-25%. Then microwave treatment for 10-30 minutes; wherein, the log is suitable for any wood, including poplar, birch, nanmu, eucalyptus, fir, pine and the like.

[0017] (2) Preparation of wood modifier: Add 20-40 parts by mass of nano-calcium carbonate and 0.5-2 parts by mass of surfactant into the mixer, then add 300-400 parts by mass of water, at a temperature of 60°C-85°C , Stir at a high speed of not less than 6000r / min for 20-50min, then ultrasonically disperse at 60°C-75°C for 10-20min, then add 10-15 parts by mass of sodium oct...

Abstract

The invention discloses a nano calcium carbonate / wood composite material production method including the five steps of pretreatment of wood, preparation of a wood modifying agent, preparation of a wood modifying liquid, dipping treatment, and post drying treatment, and the wood modifying agent includes nano calcium carbonate, a surface active agent, water, sodium octoborate, diammonium phosphate, boric acid, ammonium molybdate, carbendazim, dodecyl dimethyl benzyl ammonium chloride, imidacloprid, and sodium dodecyl sulfate, and the surface active agent is one of fatty alcohol polyoxyethylene ether, polyoxyethylene amide, and sodium dodecyl benzene sulfonate. The beneficial effect is that the nano calcium carbonate / wood composite material production method has simple process, high efficiency, environmental friendliness and low cost and other advantages, and by use of the nano calcium carbonate for modification, the nano calcium carbonate / wood composite material has good enhancement, weighting, anti-erosion, stability improvement and the like.

Description

technical field [0001] The invention relates to the technical field of wood production, in particular to a production method for preparing nanometer calcium carbonate / wood composite material. Background technique [0002] As a natural and renewable resource, wood has the advantages of beautiful texture, natural color, comfortable texture, good plasticity, and easy processing, so it is used as an ideal material for building decoration and furniture manufacturing. However, due to long-term contact with oxygen, light, and moisture, wood is prone to shrinkage and swelling, poor dimensional stability, and easy to change color, crack, wear and bruise, and is also easy to burn and be eaten by insects. Therefore, the modification of wood has been widely concerned for a long time. Nano-calcium carbonate has a good impact-reinforcing effect, and has high chemical stability, thermal stability and non-migration, and is cheap. A nano-calcium carbonate / wood composite material prepared b...
